# Simulator project for LVGL embedded GUI Library
|
|
|
|
The [LVGL](https://github.com/lvgl/lvgl) is written mainly for microcontrollers and embedded systems, however you can run the library **on your PC** as well without any embedded hardware. The code written on PC can be simply copied when your are using an embedded system.
|
|
|
|
This project is configured for [VSCode](https://code.visualstudio.com) and only tested on Linux, although this may work on OSx or WSL. It requires a working version of GCC, GDB and make in your path.
|
|
|
|
To allow debugging inside VSCode you will also require a GDB [extension](https://marketplace.visualstudio.com/items?itemName=webfreak.debug) or other suitable debugger. All the requirements, build and debug settings have been pre-configured in the [.workspace](simulator.code-workspace) file.
|
|
|
|
The project can use **SDL** but it can be easily relaced by any other built-in LVGL dirvers.
|
|
|
|
